Organ epigenetic memory

This 2018 Japanese review subject was the relationships of organ memory and non-communicable diseases:

“Organ memory is the engraved phenotype of altered organ responsiveness acquired by a time-dependent accumulation of organ stress responses. This phenomenon is known as “metabolic memory” or “legacy effect,” which is similar to neuronal and immune memory.

Not only is the epigenetic change of key genes involved in the formation of organ memory but the alteration of multiple factors, including low molecular weight energy metabolites, immune mediators, and tissue structures, is involved as well. These factors intercommunicate during every stress response and carry out incessant remodeling in a certain direction in a spiral fashion through positive feedback mechanisms.

The systematic review revealed that each intervention type, that is:

  • Glucose lowering,
  • Blood pressure lowering, or
  • LDL-cholesterol lowering,

possessed unique characteristics of the memory phenomenon. Most of the observational periods of these studies lasted for > 10 years. Memory phenomenon was suggested to last for a long time and is thought to have a considerable effect on the clinical course of NCDs [non-communicable diseases].

Organs cannot possess consciousness, so it might not be appropriate to consider whether a recalling process exists in organs. However, the properties of organs are incessantly altered by external stimuli loaded on organs as if it is updating.

It is clinically important to investigate whether organ memory can be updated by our behaviors. Once organ memory is established in an organ, organ memory in each organ can influence one another and affect organ memory in a different organ.

Epigenome-modification enzymes, such as histone deacetylases and DNA methyltransferases, and transcription factors seem to be essential for the epigenetic regulation of gene expression, which is involved in the generation of organ memory. Cellular metabolism can epigenetically modulate the expression of genes that are related to the progression of diseases.”


The reviewers asserted:

“Organs cannot possess consciousness, so it might not be appropriate to consider whether a recalling process exists in organs.”

Memory studies don’t require this consciousness to investigate even the brain organ’s areas and functions. Researchers observe memory by measuring stimulus/response items like neuron activation and various levels of behavior. Consciousness is an emergent property.

Regarding recall: An organ’s “engraved phenotype of altered organ responsiveness” may not have recall itself, but it doesn’t have a separate existence apart from its body. An organ can’t be removed from its body for very long and still be part of its body.

When an organ is in its normal state as part of a body, it has access to recall-like functions via the “inter-organ communication of organ memory.” The review also mentioned:

“Organ memory in each organ can influence one another and affect organ memory in a different organ.

Evolution didn’t support unnecessary duplication for a kidney’s memory to include recall because it’s part of a body that includes a brain that has recall. Evolution didn’t duplicate functions of a kidney’s memory in a brain, either.

Unindexed comment links?

It’s dawned on me that although links in blog posts are indexed by search engines, links in comments may not be. Here’s a post to elevate links in three comments that may have escaped notice.


From A review of biological variability:

“It is my view that all researchers have a narrow focus on what they want to research, without having an over-riding paradigm in which to fit the research and its results. Janovian Primal Therapy and theory, with its focus and understanding of the three different levels of consciousness would provide for a much needed over-arching paradigm, especially in the area of mental health.”

Congratulations on an excellent podcast, Gil!

From Remembering Dr. Arthur Janov:

“You are right on. The Norcross survey, in particular, is utter crap. More than half of those “experts” surveyed were CBT therapists who knew nothing about PT and yet deemed themselves confident to judge “primal scream therapy” as “discredited.” I feel the therapy will never be understood for what it is.”

Thanks for the detailed explanation, Bruce!
The Worst Comparative Psychotherapy Study Ever Published


From How one person’s paradigms regarding stress and epigenetics impedes relevant research:

“There is of course, reversibility. Michael Meaney’s baby rats had their epigenetic changes reversed with loving maternal care. There are several compounds in development which have been shown to reverse methylation. This former physician and researcher says, “Epigenetic changes affect the level of activity of our genes. Genetic activity levels affect our emotions, beliefs, and our bodies. Exploring epigenetics and chronic illness may help us understand causes that many of us suspect have played a role in the onset and evolution of our illnesses. Furthermore, these epigenetic changes have been found to be reversible, at least some of the time, even with a seemingly indirect treatment such as psychotherapy.” Epigenetics and Chronic Illness: Why Symptoms May Be Reversible

I looked up the psychotherapy references and found this: Serotonin tranporter methylation and response to cognitive behaviour therapy in children with anxiety disorders (reversible even with CBT, the weakest therapy of all!)

And this:
MAOA gene hypomethylation in panic disorder—reversibility of an epigenetic risk pattern by psychotherapy (also CBT)

So what gives? I suspect that your researcher is working with his/her head in the sand, hamstrung by their ideological biases. If CBT can effect epigenetic changes, imagine what primal therapy can do.”

Ideaesthesia!

This 2018 UK review subject was colored-hearing experiences from music:

“Music-colour synaesthesia has a broad scope encompassing not only tone-colour synaesthesia elicited on hearing individual tones, but a complex and idiosyncratic mixture of phenomenological experiences often mediated by timbre, tempo, emotion and differing musical style.

The possession of synaesthesia or absolute pitch was shown to have very little effect on the actual colours chosen for each of the musical excerpts, but it might be reasonable to expect that music that elicits a strong emotional response may be more likely to induce synaesthesia than music that does not.

The examination of eight neuroimaging studies were found to be largely inconclusive in respect of confirming the perceptual nature of music-colour synaesthesia. Neither the hyperconnectivity nor the disinhibited feedback theory currently holds as a single categorical explanation for synaesthesia.

Theories promoting the notion of ‘ideaesthesia’ have highlighted the importance of the role of concept and meaning in the understanding of synaesthesia..and a replacement definition: Synaesthesia is a phenomenon in which a mental activation of a certain concept or idea is associated consistently with a certain perception-like experience.”

Much of the review was philosophizing and casting around for clues. The review cited interesting studies and reviews, including The Merit of Synesthesia for Consciousness Research.


One relevant element missed by the underlying research and the review was critical periods of human development. A cited reference in How brains mature during critical periods was Sensitive periods in human development: Evidence from musical training (not freely available) which illuminated some aspects of the research:

“In contrast to a critical period, where a function cannot be acquired outside the specific developmental window, a sensitive period denotes a time where sensory experience has a relatively greater influence on behavioral and cortical development. Sensitive periods may also be times when exposure to specific stimuli stimulates plasticity, enhancing changes at the neuronal and behavioral levels.

The developmental window for absolute pitch may be more similar to a critical than a sensitive period.

The auditory cortex appears to have an unusually long period of developmental plasticity compared with other sensory systems; changes in its cellular organization and connectivity continue into late childhood.

The effects of musical training have been shown to impact auditory processing in the brainstem as well.”

Let’s say that a researcher wanted – as one cited study did – to examine absolute pitch, a rare trait, present in a subset of synesthetes – music-color, another rare trait. The study as designed would probably be underpowered due to an insufficient number of subjects, and it would subsequently find “very little effect.”

Let’s say another researcher focused on brain areas in the cerebrum, and like the eight cited studies, ignored the nuclei in the pons part of the brainstem which are the first brain recipients of sound and equilibrium information from the inner ear via the eighth cranial nerve. Like those studies, the researcher was also biased against including limbic brain areas that would indicate “a strong emotional response.” A study design that combined leaving out important brain-area participants in the synesthesia process with a few number of synesthetes would be unlikely to find conclusive evidence.

The reviewer viewed the lack of evidence from “eight neuroimaging studies” as indicating something about the “perceptual nature of music-colour synaesthesia.” An alternative view is that the “inconclusive” evidence had more to do with study designs that:

  • Had a small number of subjects;
  • Omitted brain areas relevant to the music-color synesthesia process;
  • Didn’t investigate likely music-color synesthesia development periods; and
  • Didn’t investigate associations of music-color synesthesia with epigenetic states.

Consider the magnitude of omitting the thalamus from synesthesia studies as one “perceptual nature” example. Just the background information of Thalamus gating and control of the limbic system and cerebrum is a form of memory indicated its relevance to synesthesia:

Despite the fundamental differences between visual, auditory and somatosensory signals, the basic layouts of the thalamocortical systems for each modality are quite similar.

For a given stimulus, the output neural response will not be static, but will depend on recent stimulus and response history.

Sensory signals en route to the cortex undergo profound signal transformations in the thalamus. A key thalamic transformation is sensory adaptation in which neural output adjusts to the statistics and dynamics of past stimuli.”

One of this study’s researchers described ways that an individual’s “stimulus and response history” became unconscious memories with the thalamus. Including the thalamus in synesthesia studies may also have findings that involve reliving or re-experiencing a memory, possibly an emotional memory.

In such future research, it could be a design element to ask synesthetes before and after the experiment to identify feelings and memories accompanying synesthesia experiences.

It shouldn’t be a requirement, however, to insist that memories and emotions be consciously identified in order to be included in the findings. Human studies, for example, Unconscious stimuli have a pervasive effect on our brain function and behavior have found:

“Pain responses can be shaped by learning that takes place outside conscious awareness.

Our results support the notion that nonconscious stimuli have a pervasive effect on human brain function and behavior and may affect learning of complex cognitive processes such as psychologically mediated analgesic and hyperalgesic responses.”

A flying human tethered to a monkey

Ponder this drone photo of “a flying human tethered to a monkey” ground drawing made over 1,000 years ago as reported by National Geographic and excerpted by the Daily Star:
Flying human tethered to a monkey


Aren’t the geoglyph and its description pretty good expressions of our evolved condition? Especially since it’s the interpretation of people who lived more a millennium ago?

With so many information sources freely available now, one couldn’t successfully argue that they understood the world better than we do, though. The price paid for figuring things out today is our “flying human” time and efforts, without which we’re as ignorant as our “monkey.”

A few aspects of the current comprehension of the differences between our two pictured primates are in Genetic imprinting, sleep, and parent-offspring conflict:

“I remain skeptical of a tendency to ascribe most modern woes to incongruence between our evolved nature and western cultural practices. We did not evolve to be happy or healthy but to leave genetic descendants, and an undue emphasis on mismatch risks conflating health and fitness [genetic rather than physical fitness].”

Our “flying human” can make happiness and health choices that our “monkey” can’t:

Our genetic adaptations often try to fool us into doing things that enhance fitness at costs to our happiness.

Our genes do not care about us and we should have no compunction about fooling them to deliver benefits without serving their ends.

Contraception, to take one obvious example, allows those who choose childlessness to enjoy the pleasures of sexual activity without the fitness-enhancing risk of conception.”

Other aspects of each of our two pictured primates’ differences are illuminated in a reference to A study of DNA methylation and age:

“Aging is not and cannot be programmed. Instead, aging is a continuation of developmental growth, driven by genetic pathways.

Genetic programs determine developmental growth and the onset of reproduction. When these programs are completed, they are not switched off.

Aging has no purpose (neither for individuals nor for group), no intention. Nature does not select for quasi-programs. It selects for robust developmental growth.”

The epigenetic clock theory of aging cited the same author, and modified his point to say:

“The proposed epigenetic clock theory of ageing views biological ageing as an unintended consequence of both developmental programmes and maintenance programmes.”

Finally, our “flying human” can make choices that aren’t available to our “monkey” concerning the structure, direction, and duration of our one precious life:

“What are you doing to reverse epigenetic processes and realize what you want? Do you have ideas and/or behaviors that interfere with taking constructive actions to change your phenotype?”

What are the chances?

This 2018 UC Davis anthropology study was on dice changes over two centuries:

“In Roman times, many dice were visibly lopsided..It did not matter what the objects were made of (metal, clay, bone, antler and ivory), or whether they were precisely symmetrical or consistent in size or shape, because, like the weather, rolls were predetermined by gods or other supernatural elements.

Dice, like many material objects, reflect a lot about people’s changing worldviews, Eerkens said. In this case, we believe it follows changing ideas about chance and fate.”


Think of a significant event in your life. Was it brought about by:

  • Fate?
  • Karma, divine intervention?
  • A prayer, belief, placebo-effect process?
  • Randomness?
  • A coin-flip, card-draw, dice-roll decision process?
  • A weighted-probability decision process?
  • Chosen behavior, thoughts, and feelings?
  • Unconscious behavior, thoughts, and feelings?
  • Culturally-guided motivations?
  • Non-arbitrary influences of other parties?

Which one or more of these factors would you now prefer to have been involved?

Your need to feel important will run your life, and you’ll never feel satisfied

Yesterday’s team meeting at work provided one display after another of a person’s need to feel important. These eye-openers were the reason the scheduled 30-minute meeting lasted 45 minutes.

Although half of the forty or so attendees are under the age of 40, curiously, only two of them spoke during the meeting. I wasn’t among the older people who had something to say.

Not that I wasn’t tempted by the team-building exercise with its Skittles prompts:

  • Red – Tell us something you do well
  • Orange – Tell us something about your childhood
  • Purple – What could you live without?
  • Yellow – What couldn’t you live without?

Participation in the exercise was voluntary. Yes, I drew an orange Skittle.

Everyone knew there wasn’t enough time for each of us to speak and have the exercise become team-building, yet a dozen people piped up. Every one of the self-selected responses could have been prefaced with “I’m important because..”



There are many needs a person develops and tries to satisfy as substitutes for real needs that weren’t fulfilled. In this blog I’ve focused on the need to feel important.

I started with How do we assess “importance” in our lives? An example from scientists’ research choices and highlighted it on my Welcome page:

“Do you agree that an individual’s need to feel important is NOT a basic human need on the same level as nourishment, protection, and socialization? How does this need arise in our lives?”

I supported an explanation of the need to feel important with evidence and arguments on my Scientific evidence page and said:

“If the explanation is true yet someone rejected it, they at least wouldn’t have suffered from exposure to it. They’ll just remain in our world’s default mode of existence:

  1. Unaware of their own unconscious act-outs to feel important;
  2. Unaware of what’s driving such personal behavior; and
  3. Uninformed of other people’s behavioral origins as a consequence of 1 and 2.”

Other examples of substitute needs include:

What do you think? Any arguments for or against interrupting people’s default mode of existence?
